Stainless Steel Tube Information: ASTM A312 TP304L Stainless Steel Tube with Good Chemical Composition and Mechanical Properties
The chemical composition and mechanical properties of ASTM A312 TP304L stainless steel pipes are as follows:
Chemical composition (mass fraction%)
table
Element content requirements
Carbon (C) ≤ 0.030
Silicon (Si) ≤ 1.0
Manganese (Mn) ≤ 2.0
Phosphorus (P) ≤ 0.045
Sulfur (S) ≤ 0.030
Chromium (Cr) 18.00-20.00
Nickel (Ni) 8.00-12.00
Note: TP304L is an ultra-low carbon austenitic stainless steel, with "L" representing Low Carbon. By reducing the carbon content, it effectively reduces the precipitation of chromium carbide during welding, thereby improving the intergranular corrosion resistance.

Performance indicator requirements
Yield strength (YS) ≥ 175 MPa
Tensile strength (TS) ≥ 480 MPa
Elongation after fracture (EL) ≥ 40%
Brinell hardness (HV) ≤ 200
This material has good toughness, formability, and weldability, and can maintain stable performance in both high and low temperature environments. It is suitable for temperatures ranging from -196 ℃ to 800 ℃.
